End Date not saved properly for existing nodes

I noticed that often when I edit a node in a repeat sequence, the ending time gets hosed up somehow in all of the nodes. So I was scanning the code and noticed that the start hour, minute and second gets saved, but not the ending hour, minute and second in the _eventrepeat_save_repat function starting at about line 1556.

So my question is this, is there a reason we are not saving the ending time along with the date?

      //loop through the new sequence, mapping the start/end dates
      //from the old sequence to the new pattern
      while (($new_date = db_fetch_object($update_render_dates)) && ($old_date = db_fetch_object($old_render_dates))) {
        //here we generate new start and end timestamps for the node,
        //based on present new render sequence and the start and end
        //time of the node from which the edit is being performed,
        //accounting for timezone offsets
        $start_time = event_explode_date($new_date->date);
        $start_time['hour'] = $start['hour'];
        $start_time['minute'] = $start['minute'];
        $start_time['second'] = $start['second'];
        $end_time = event_implode_date(event_date_later($start_time, event_duration($start, event_explode_date($node->event['end_orig']))));
        $start_time = event_implode_date($start_time);

        //update the event start and end time TODO: event times are
        //getting adjusted here (possible cause of double shift)
        db_query("UPDATE {event} SET event_start = '%s', event_end = '%s' WHERE nid = %d", $start_time, $end_time, $old_date->nid);
        $last_rendered = $new_date->date;
      }
